2.3.3 Configuring Static ARP Entries in a VLAN

In the scenario where two users belong to the same VLAN but user isolation is configured in
the VLAN, to implement communications between the two users, you need to enable static ARP
within the VLAN on the interface of the VLAN.
Context
If static ARP and the Virtual Router Redundancy Protocol (VRRP) are enabled on a device
simultaneously, the virtual IP address of the VRRP backup group configured on the VLAN
interface cannot be the IP address contained in the static ARP entries; otherwise, incorrect host
routes are generated and thus packets cannot be normally forwarded.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Configure static ARP entries in a Virtual Local Area Network (VLAN).
To configure static ARP entries in a VLAN, do as follows:
l Run the arp static ip-address mac-address vid vlan-id interface interface-type interface-
l Run the arp static ip-address mac-address [ vpn-instance vpn-instance-name ] vid vlan-

NOTE
Static ARP entries keep valid when a device works normally.
NOTE
To configure static ARP for the packets with double tags, run the arp static cevid command. For details,
see the S9300&S9300E Terabit Routing Switch Command Reference - Ethernet.
number command.
It is required to set parameters vid vlan-id and interface interface-type interface-number when
you configure static ARP entries in the VLAN.
If the interface corresponding to the VLAN is bound to a Virtual Private Network (VPN),
the device can automatically associate the configured static ARP entry with the VPN. This
command is applicable to port-based VLANs.
